Question

why an atom Acquires magnetic moment?​

Answer 1

Answer:

The magnetization currents in materials are a consequence of the electron's orbital motion and spin. ... When any material is placed into a magnetic field its atoms acquire an induced magnetic moment pointing in a direction opposite to that of the external field. The material becomes magnetic.
